Geolocation correction using of FY-3A atmospheric infrared sounder remote sensing image
扫描参数校正模型在FY-3A 红外分光计遥感图像定位校正中的应用

The general rule of deviations existed in the geolocation results of atmospheric infrared sounder (IRAS) image were investigated . The influence of scanning parameter deviation on geolocation was quantitatively analyzed by using scanning parameter correction model. A reference scheme was proposed to correct the geolocation deviation of AIRS images.It is shown that the corrected geolocation result is coincident with the World Geography Base Map and the feasibility of the scheme was verified.
